Application June 17, 1949, Serial No. 99,731

2 Claims.

T-his invention relates to a belt preserving device and more particularly to a belt cleaning and preserving leather machine belts and the like.

It is an object of this invention to'provide a pair of brushes to be supported on the belt driving or driven machine for engagement on the opposite sides of the machine belt for brushing and cleaning the operative surfaces and applying a proper leather lubricant to both sides of the belt.

Another object of this invention is to provide a leather belt preserving device of the kind to be more particularly described hereinafter having a fountain type brush for applying the leather lubricant to one surface of the brush and having a second brush, cooperating with the fountain brush for applying the lubricant to the other side of the belt.

Still another object of this invention is to provide a leather belt preserving device of this kind for cleaning and lubricating leather machine belts in a manner to preserve the useful life and operation of the belts in a manner to constitute a considerable saving in time, labor, and money, while more efficiently cleaning the belt and applying the lubricant than by the manual methods heretofore used for similar purposes.

With the above and other objects in view, my invention consists in the novel combination, arrangement and details of structure set forth in .the specification and drawings, and then more particularly described in the appended claims.

In the drawings:

Figure l is a perspective view of a leather belt preserving device, constructed according to an embodiment of my invention.

Figure 2 is a transverse section taken on the line 2-2 of Figure 1.

Figure 3 is a side elevation of the belt preserving device.

Referring to the drawings, the numeral Ill designates generally a leather belt preserving device constructed according to an embodiment of my invention for cleaning leather machine belts and applying a proper liquid lubricant thereto during the operation of the machine using the belt.

The belt preserving device I is formed with a suitable ring or bracket II which is adapted to be fixedly secured on a fixed and stationary support on or adjacent to the machine, not shown in the drawings. The ring or bracket II is formed with an outwardly extending lug 12 on one side thereof through which 'a bolt or threaded post I4 is adapted to be vertically extended. A set screw I5 is threadably engaged in the stud or lug i2 for clampingly securing the post M in a selected vertically adjusted position on the supporting member I I.

An upper fountain brush it is carried by the post 14 at the upper end thereof for engagement .with the upper surface of a belt, not shown in the drawings, to be engaged therewith. The brush I6 is formed with a rigid back i! made of wood, plastic, metal or other suitable rigid material having a plurality of downwardly opening recesses [8 on the lower side thereof. A bristle formation i9 is adapted to befixedly engaged in each of the receses l8 and extended downwardly from the back ll. An enlarged recess or bore 20] is formed through the back I! and an internally threaded plug or pipe element 2| is adapted to be engaged in the upper end of the bore. A suitable absorbent element or wick, such as felt or the like 22 is, engaged in the lower end or the recess 20, above the center portion of the central bristle formations l9 and the recess iii of the center bristles 19 are disposed in communication with the absorbent body 22. A flange 24 is fixed to or formed integral with the upper end of the plug 2| and overlies the upper surface of the back I! to be secured thereon by bolts 25 or other suitable fastening means.

A suitable container 26, shown in dotted lines in Figure 1, is formed with a threaded neck for threaded engagement with the fitting or plug 2| for removably securing the belt lubricant containing container body thereto. The lubricant in the body is adapted to flow from the neck of the container 26 into the absorbent body or pad 22 thence to the bristles 19 which are formed of suitable absorbing material for spreading the lubricant throughout all of the bristles carried by the back H.

A bracket 21 is fixed on one end of the back I! and is formed with an internally threaded boss '28 extending outwardly therefrom. The

boss 28 is threadably engaged on one end of a,

threaded bolt or supporting member 29. A suitable bracket 30 is fixed on the other end of the bolt 29 and formed with an opening through which the post I4 is slidably engaged. The

bracket 30 is secured in a selected adjusted posi I 6. The lower brush 33 is formed with a rigid back 35 having upwardly extending bristles 36 on the upper face thereof disposed in facing and confronting relation with the depending bristles IQ of the fountain brush 16. A bracket 31 is fixed on one end of the back 35 and has secured thereon an internally threaded boss or sleeve element 38. The sleeve member 38 is threadably engaged on the outer end of a lower bolt 39 carried by the lower end of the post I4. An apertured bracket 40 is fixed on the other end of the bolt 39 and is slidably engaged on the lower end 34 of the post ll to be secured thereon in a selected adjusted position between the lock nuts 4|, threadably engaged on the lower end 34 of the post l4.

The upper fountain brush I6 is secured in a selected rotated and threaded position on the.

bolt 2'9 by a lock nut 42 and the lower brush 33 is secured in its selected rotated position along the length of the bolt 39 by a lock nut 44.

In the use and operation of the belt preserving device III, the lubricant containing receptacle 26, is threadably engaged in the pipe element 2| of the brush H5. The brushes l6 and 33 are adjusted vertically on the post I4 and horizontally on the bolts 29 and 39 respectively for disposing the depending bristles l9 of the fountain brush in engagement with the upper surface of the belt to be cleaned and lubricated, while the upwardly' extending bristles 36 of the lower brush 33 are positioned for engaging the lower surface of the belt and engaging certain of the bristles I9 of the upper brush "3 at at least one end of the brushes on opposite sides of the belt engaged therebetween. As the bristles l9 and 36 are of absorbent material, the engagement of the bristles with each other will constitute a means for conducting or conveying the lubricating fluid from the container 26 to both sides of the belt engaged between the brushes.

I claim:

1. A leather belt preserving device comprising a supporting element for attachment to a fixed support adjacent to a belt to be lubricated, a screw post carried by said supporting element, a fountain brush adjustably mounted on said post for applying a belt lubricant on one side of the belt, a second brush adjustably mounted on said post confronting said fountain brush and engageable therewith in lubricant absorbing relation for applying the lubricant on the other side of the belt engaged therebetween.

2. A leather belt preserving device comprising a supporting post, a pair of brushes positioned transversely of said post and each mounted on said post for traveling movement therealong into and out of contacting relation with respect to each other and for rotative movement with respect to each other, an absorbent wick carried by the backing of one of said brushes and having one end in communication with the adjacent bristles, and means on the backing of said one of said brushes and in communication with the other end of said wick for applying lubricant to said wick, each of said brushes including a backing and a plurality of bristles dependingly secured to said backing, the bristles being arranged so that the bristles of the one brush face the bristles of the other brush and receiving therebetween a belt to be lubricated when the bristles are in contacting relation with respect to each other.
